Roof shingles are a popular roofing choice that’s durable and protects buildings from the weather. They’re usually made of asphalt, wood, metal, or synthetic materials. Asphalt shingles are the most popular type, offering a good balance of cost, durability, and looks. Shingles are laid in overlapping rows to create a protective layer on the roof. They’re built to withstand harsh weather like rain, snow, wind, and hail. Shingles also provide insulation and help keep the building’s temperature steady.
